User manual ELECTRO-VOICE XI-1082 EDS

[. . . ] While neodymium drivers provide unmatched output capabilities, the advanced RMDTM technology used in X-Array InstallTM produces world class sound reinforcement at very high levels. Applications The Xi-1082 loudspeaker system is ideal for any professional touring or installation application requiring accurate, high-level, sound reinforcement. Because of the unique performance capabilities featured in this system, the X-Array InstallTM Xi-1082 offers extremely wide-range music reproduction as well as accurate vocal coverage and maximized intelligibility. [. . . ] Architects' And Engineers' Specifications The loudspeaker system shall be a two-way, vented type, consisting of a 203-mm (8. 0 in. ) direct-radiating driver with a compression driver with a 25. 4-mm (1. 0 in. ) exit mounted on a 90° x 40° constant-directivity horn. Power handling shall be 175 watts of pink noise with a 6-dB crest factor for eight hours (as per ANSI/EIA RS-426-A 1980 standard). Frequency response shall be smooth and usable at high SPL levels from 50 Hz to 20 kHz with pressure sensitivity of 91 dB for 1 watt at 1 meter. Impedance shall be 8 ohms nominal, 6 ohms minimum. The system shall have a distribution pattern with 90° nominal horizontally from 3 kHz to 16 kHz and 40° nominal vertically from 3 kHz to 20 kHz. The loudspeaker enclosure shall be constructed of 18-mm thick plywood, trapezoidal in shape, internally lined with sound-absorbing material. The finish of the enclosure 2 X-Array InstallTM Xi-1082 Loudspeaker System shall be textured black. A black metal removable grille with foam backing shall be provided. The loudspeaker enclosure dimensions shall be 488-mm (19. 23 in. ) high, 235-mm (9. 25 in. ) wide (front), 150-mm (5. 9 in. ) wide (back) and 285-mm (11. 23 in. ) deep.

X-Array InstallTM Xi-1082 Loudspeaker System Figure 1-- Polar Response The directional response of the system was measured in an anechoic environment at a distance of 6. 1 m (22 feet) using 1/3-octave-filtered pink noise with a full spherical measurement system. The polar response of the loudspeaker system at selected 1/3-octave frequencies is shown. [. . . ]
